Embodiment Construction

[0011] The invention relates to a control method for vertical lifting and horizontal movement of a work bucket of an aerial work platform. The aerial work platform is composed of three parts: a chassis, a platform and an arm frame, wherein the heights of the chassis and the platform are fixed. The method is as follows: a length sensor and an angle sensor are installed on the jib to detect the current state of the jib of the aerial work platform and transmit it to the controller. When the function of "vertical lift and horizontal movement" needs to be realized, turn on the switch. When the staff operates the luffing handle, the luffing and stretching will be output at a certain ratio at the beginning, and this value can be adjusted. The controller is based on the current state - arm length l 0 with angle θ 0 Calculate its magnitude e 0 , and record, where e 0 = l 0 ×Cosθ 0 . During the working process of the boom, the sensor continuously transmits the working parameters o...

Abstract

The invention relates to a method for controlling vertical lifting and horizontal movement of an aloft work platform operating bucket, which comprises the steps of installing a length sensor and an angle sensor on an arm support of an aloft work platform for sensing the current state of the aloft work platform arm support and transmitting to a controller; opening a switch when requiring to realize the 'vertical lifting and horizontal movement' function;, calculating the amplitude e0 of the amplitude handle by the controller based on the current state when an operator operates a variable amplitude handle, and recording; continuously transmitting operating parameters of the system by the sensors during the operation process of the arm support to the controller to ensure the vertical lifting of the operating bucket; calculating the height h0 of the expansion handle by the controller when the operator operates an expansion handle, and recording; and continuously transmitting the operating parameters of the system by the sensors during the operation process of the arm support to the controller to ensure the horizontal movement of the operating bucket. The vertical lifting and the horizontal movement are independent of each other. The operation track of the aloft work platform operating bucket is controlled by the controller; and has the advantages of precise control, convenient operation and remarkably improved operating efficiency.

Description

technical field [0001] The invention relates to a working method of a work bucket of an aerial work platform. It belongs to the technical field of engineering machinery. Background technique [0002] At present, the control method of the general aerial work platform is that one operation command controls one action. The luffing command controls the luffing cylinder of the aerial work platform to raise or lower the working arm; the telescopic command controls the telescopic cylinder of the aerial work platform to extend or retract the working arm. These two sets of actions are independent of each other and cannot be linked. The so-called vertical lifting of the working bucket means: keep the amplitude of the aerial work platform unchanged, and compensate for the expansion and contraction when the working bucket is lifted and lowered, so that the working bucket can maintain a constant range of lifting; the so-called horizontal movement of the working bucket means: keep the he...
